how to fix this?

Hi. I have updated code and README. Please try running again and let me know if there are issues. Use final_saket type images for testing.

It is not able to find image. Please enter correct path

[leisther]

python code2.py -i1 /home/leisther/Downloads/Body-Measurement-using-Computer-Vision-master/Images/final_saket1.jpg -i2 /home/leisther/Downloads/Body-Measurement-using-Computer-Vision-master/Images/final_saket2.jpg -i3 /home/leisther/Downloads/Body-Measurement-using-Computer-Vision-master/Images/final_saket3.jpg -a "True"

I haven't solve the error NULL window handler in function 'cvSetMouseCallback' any idea of what to do with this?

[ankesh007]

I am not sure of what this error means. Maybe google.

I'm not sure, but it could be because of OpenCV version as the project is made in version 2.4.13.6 and we're using a higher version(for me its 4.0.0)

@KishorePyDev
For sure you will get the error
print(img.shape) is the answer

@leisther, simply add
cv2.namedWindow(window_name1) before cv2.setMouseCallback(window_name1, click_and_crop)

@leisther, replace
clone = image.copy() with clone = np.copy(image)
